LCD backlight unit - Electro-optical measurement methods of LED backlight unit1 Scope This part of IEC 62595 series specifies the standard measurement conditions and measuring methods for determining electrical, optical, and electro optical parameters of LED backlight units for liquid crystal displays. NOTE Other backlights (Cold Cathode Fluorescent Lamps (CCFLs), External Electrode Fluorescent Lamps (EEFLs), Hot Cathode Fluorescent Lamps (HCFLs), Carbon Nano Tube (CNT), etc.) are excluded from this standard.

These test methods are intended to be referenced in standards for cable construction and for cable materials

The reference method is the automatic one

BS EN 4535-2 specifies the characteristics of bushes flanged in aluminium alloy with self-lubricating liner elevated load for aerospace applications

This International Standard specifies a method for the quantitative determination of phospholipids content by high performance liquid chromatography (HPLC) using a diol column and a light-scattering detector

BS EN 16848 on Bio-based products are useful for:

Industrial process control valves are excluded from this European Standard

cranes and offshore topside structures

NOTE In countries not in a position to use the gas-chromatographic method

the procedures in this document are not applicable to acceptance assessment of lots

BS EN 61300-3-32 is useful as it provides guidance on the polarization mode dispersion measurement for passive optical components

including balanced and unbalanced parts)

Note 3: BS EN 50545-1 does not apply for the following applications and technologies:
